IMPROVED CLOTH ES-WPsINGER.

Specification forming part of Letters Patent No. 42,908, dated May 24,1864.

T0 all whom it may concern.-

Be it known that I, DANlEL D. Grrr, of Arendtsville, in the county ofAdams and State of Pennsylvania, have invented certain new and usefulImprovements in Clothes- I/Vringers; and I hereby declare that thefollowing is a full, clear, and exact description ofthe same, referencebeing had to the accompanying drawing, which represents a perspectiveview of a clothes-wringer embodying the principles of my invention,certain parts having no bearing on the invention subjectmatter of thispatent-such as themeans of attachment, spring-regulating device forcompressing the rollers, &c.-bein g omitted.

My invention relates to the method of driving the rolls of wringing andmangling machines and other kindred implements, and has for its objectthe transmission of movement of a crank or its equivalent to the rollsso as to allow of their moving within certain limits from and towardeach other, according to the thickness of the material which is beingpassed through between them, without disturbing the action of thecog-wheels or gearing mechanism. This was heretofore effected by thepeculiar construction of thecog-wheels,theteeth of which were so formedas to allow of the cogs of the one wheel to slide upon those of theother without coming out of working contact; but this it was found ofdifficult application to small wringers, in which the cogwheels for thepurpose of requisite speed are necessarily small. By my improvement Iamenabled to produce the same result on wringers, whether small or large,at less cost of construction and without liability of getting out oforder; and my invention consists, rst, in the combination inwringing-machines of a rotary driving mechanism set in fixed bearingswith rolls, the axles of either or both of which are held in movablebearings; second, in combining, in wringing-machines, with gearwheelsrotating in fixed bearings and rolls r0- tating in movable bearings, alinked or flexible connection; third, in the combination, inwringing-machines, of a pair of rolls with fixed gear-wheels when one ofthe rolls rotates in xed bearings and is rigidlyconnected with itscorresponding gear-wheel, while the other is rotating in movablebearings and is connected with its corresponding gear-wheel by means ofaflexible or link connection; fourth in the construction of the frame ofa wringing-machine with a standard or standards for the gear mechanism,separate and independent from the standards of the rolls; fifth,linconnecting, in wrin gin g-machines, the shaft of the driver of thegear-wheels with the shaft of the corresponding roll by means of auniversal joint.

To enable others to make and use my invention, I shall now proceed todescribe the construction and operation of the same.

Referring to the drawings, A is the frame of my improvedwringer. that ofmost wringers, of standards slotted to admit of the boxes orjournal-blocks of the rolls and braced laterally to afford the requisitestrength and rigidity. The frame is or may be provided, as usual, withthe legs cg other means of attachmentto the tub and with springs orscrews or other devices for regulating the pressure between the tworolls. The latter, not pertaining to this my invention, are omitted inthe drawings.

In addition to the main standards holding the rolls, as shown, there isa third standard, B, which is connected with roll-frame by means ofcross-pieces or side braces, C, extending to the one side of the frame.This standard contains the bearings of the gear-wheels D D, and may bearranged to support the journals or axles on one or both sides of thewheels. In this instance the standard is shown oomposed of twointernally-recessed uprights bolted or otherwise secured together,supporting the axles ou both sides and inclosing the wheels for theirbetter protection. The two Wheels D and D are thus arranged in fixedrelation to each other. The former is mounted on a shaft which, beingalso the shaft of the lower roll, R, rests in xed bearings in the tworoll-standards, as well as in the wheel-standard. The latter, D', ismounted on a short shaft or axle, which is united with the axle or shaftof the roll R by means of a universal joint or other flexible or linkedconnection. The ends of the shaft of the roller R are secured in blocksor bearings S, confined within slots in the standards A, and are capableof an up-and-down motion therein.

From the foregoing description of the parts the operation will bereadily understood. Ro-

Itis composed, like tary motion being imparted to the crank M, Which maybe attached to or form part of the shaft common to both cog-Wheel D androll R, the two cog-Wheels, meshing into each other, Will move Withequal velocities. The roll It, being rigidly connected with the shaft ofthe Wheel D, will necessarily partake of the same movement, and theroll'I, being connected With the shaft of Wheel D by means of auniversal joint, will rotate in perfect unison therewith, although itsaxis of revolution may change its position in relation to that of theWheel. I would observe that this contrivance is susceptible of manymodifications in point of construction and arrangement of parts,

Without departure from the principle of my invention; but I havedescribed and shown one mode of carrying it into effect, which I havefound to answer the purpose it was designed for Well, and,

Having now fully described my said invention, what I claim as myinvention, and desire to secure by Letters Patent, is

1. The method herein described of operating movable rolls of awringing-machine from fixed gears by coupling either or both of theaxles of the latter with the corresponding shafts of the former by meansof aflexible connection, substantially as set forth.

2. The combination, in wringing-machines, of a rotary driving mechanismset in fixed bearings with rolls, the axles of either or both of Whichare held in movable bearings, substantially as set forth.

3. Combining, in wringing-machines, with gear-Wheels rotating in fixedbearings and rolls rotating in movable bearings, a linked or iiexibleconnection, substantially as set forth.

4. The combination, in wringing-machines,

`of a pair of rolls with fixed gear-Wheels, when one of the rollsrotates in fixed bearings and is rigidly connected with itscorresponding gear-Wheel, While the other is rotating in movablebearings and is connected With its corresponding gear-Wheel by means ofa flexible or link connection, substantially as set forth.

5. The construction of the frame of a wringing-machine with a standardor standards' for the gear mechanism separate and independent from thestandards of the rolls, substantially as set forth.

6. Connecting, in wringing-machines, the shaft of the driver of thegear-Wheels With the shaft of the corresponding roll by means of auniversal joint, substantially as set forth.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
